Pacbrake's PH+ (PowerHalt Plus) Electronic Air Shutoff System is an electronically controlled emergency engine shut down system which forces engine shut down by blocking an engine's air intake path.; Secondary trip speed for PTO and anti-theft applications - providing ground to the Secondary Trip Speed input allows users to engage a second emergency shut-down speed for use while powering auxiliary equipment or to prevent theft. (To prevent accidental shut down while enabling and disabling Secondary Trip Speed a 5 second grace period is applied when switching to a lower trip speed to allow for engine speed to reduce. When switching to a higher trip speed the change is applied immediately.); Kit Contents:; PH+ PowerGuard Controller; Application Specific Harness; Power/Switch Harness; Toggle Switch Assembly; Tie Straps; Self-Tapping Screws; Automatic shutdown is achieved by actuating the engine's existing electronic throttle unit if engine speed exceeds the pre-set speed or by manual override. The valve electronically returns to open position after emergency engine shutdown all while providing feedback to the operator that the valve is held closed via an illuminated switch.; PH+ KEY BENEFITS:; Reliable and safe emergency shut down for diesel engines with electronic throttle body: automatically via overspeed signal or manually via toggle switch (valve remains closed for minimum 15 seconds after tripping and will hold closed until removal of shut-down signal); Capable of shutting down at a secondary trip speed for special applications such as protection of PTO equipment or as an anti-theft device; In-cab switch for manual shutdown included; Auto resets after shutdown; When valve is closed supplied switch light illuminates to indicate system activation; Valve will electronically reset and switch light will extinguish upon removal of engine shut-down signal
